Windows 10: PHYSICALDRIVE numbering keeps changing between reboots for my NVMe device

I have few NVMe storage devices connected to my system.

After booting to windows,

"wmic diskdrive" command under power shell lists device with "PHYSICALDRIVE #".

But after a reboot same device comes up with a different number, which was assigned to different drive earlier. This is little confusing.

is this expected behavior?

is there a way to keep the same numbering for the device across reboots?

Thanks

AMD X370 Chipset - NVMe boot device - Driver issue

Mostly posting this in case others run into this issue.

I have an AMD Ryzen system with an Asus X370 motherboard and two SATA drives in a RAID 1 array booting from a Western Digital NVMe stick

Last night at some point the system - Newly upgraded to Windows 1903 with all available post upgrade patches - that the
Standard NVM Express Controller driver wasn't sufficient for the NVMe stick not running RAID mode (disabled in BIOS) and installed the
AMD-RAID Bottom Device and AMD-RAID Controller [Storport] drivers for it.

It did this silently. I rebooted to cure a different issue and Windows 10 ended up in a boot loop.

I only realized what actually happened after I restored a Macrium Reflect (HIGHLY RECOMMENDED) image of the C: drive (NVMe) from the night before the reboot, opened device manager and saw what it had done.

I don't know of an easy way to figure out which AMD-RAID Bottom Device
and AMD-RAID-Controller [Storport] are assigned to which device so I temporarily put the NMVe stick into RAID mode so it would boot and disabled RAID for the remainder of the SATA devices. This let me boot, change the driver back to the
Standard NVM Express Controller Driver (because now there is only one AMD-RAID Bottom Device and AMD-RAID-Controller [Storport]
listed in device manager) , disable NVMe RAID, enable SATA RAID and resolve the issue.

Whew. Now, if it boot loops again, my first troubleshooting step will be to turn on RAID mode for the NVMe stick and see if that fixes the boot issue... Instead of spending an hour trying to get the system to see the F8 key being spammed so I could select
the Reflect recovery USB stick and reimage the NMVe stick...

 

Display resolution keeps changing

Hi Rick,

It might be caused by a faulty driver that's why your display resolution keeps changing. We
suggest that you uninstall and reinstall the display driver, see steps below:

• Press Windows key + X and click on
  Device Manager.
• For graphics cards, expand the Display adapters category, right click your graphics card and select Uninstall.
• Restart your PC and Windows will attempt to reinstall the driver.

Let us know if you have any other questions.

 

reboot and select property boot device

You need to set your main Harddrive which has your Operating System on as the first harddrive to boot, if have more than one harddrive.

open Bios
boot priority
Select the OS harddrive as first boot drive , If not sure switch between them
Set correct time and date if wrong
Save and reboot

If not sure on steps , give the Make and model number of motherboard and can assist you.

Hopefully no damage to the HDD
